Zend Navigation - Mark parent active if a child is active

Question

I'm currently creating my new website using Zend Framework 1.12.3 and I saw something I hate about Zend Navigation:

When a children route is active (exemple: a blog single post, route blog-post), it doesn't mark the parent page (route blog in this case) as active.

Here's my code: (navigation.xml)

<blog>
    <label>BLOG</label>
    <route>blog</route>
    <title>BLOG_TITLE</title>
    <pages>
        <blog-post>
            <route>blog-post</route>
            <visible>false</visible>
        </blog-article>
        <blog-category>
            <route>blog-category</route>
            <visible>false</visible>
        </blog-category>
    </pages>
</blog>

In clear, I would the page blog to be marked as active if a child route like blog-post is active. It doesn't do that unfortunately without using subpages (which I don't want). So if there's a way to mark active the route name blog and all routes who start with blog (exemple: blog-post, blog-category, blog-author) it would be very useful!

I don't want to use subpage for this because of my menu partial render a empty dropdown (Twitter Bootstrap). See by yourself:

I know it's already been answered, but I found different solution, because one posted by Marshall didn't work for me. I guess it's because I am not using action/controller in my menu, but routes instead.

My menu entry looks like this:

array(
    'label' => 'cms-nav_users',
    'access_module' => 'user',
    'resource' => 'user_admin',
    'route' => 'admin_user',
    'pages' => array(
        array(
            'label' => 'cms-nav_companies',
            'access_module' => 'user',
            'route' => 'company_admin',
            'resource' => 'company_admin',
        ),
        array(
            'label' => 'cms-nav_users-list',
            'access_module' => 'company',
            'route' => 'admin_user',
            'resource' => 'user_admin',
        ),
    ),
),

I came up with a solution based on my own menu template (partial). Basically there is a foreach loop which checks if any of subpages is active and if there is one - marks parent as active, it looks like this:

$active = false;

if (!empty($page->pages))
{
    foreach ($page->pages as $subpage) 
    {
        if ($subpage->isActive()) $active = true;
    }
}

$html[] = ($active) ?  'class="active"' : '';

Hope it helps someone :)

UPDATE

Actually I found out that you can use Zend Framework's own isActive() with true parameter, as seen in source code:

Zend_Navigation_Page_Mvc::isActive($recursive = false)

Both ways will work, but this one seams more proper.

from the documentation:

array(
    'label' => 'Page 2',
    'controller' => 'page2',
    'pages' => array(
        array(
            'label' => 'Page 2.1',
            'action' => 'page2_1',
            'controller' => 'page2',
            'class' => 'special-one',
            'title' => 'This element has a special class',
            'active' => true
        ),
        array(
            'label' => 'Page 2.2',
            'action' => 'page2_2',
            'controller' => 'page2',
            'class' => 'special-two',
            'title' => 'This element has a special class too'
        )
    )
),

As you can see, the parent menu item has no action assigned to it, but the parents and children share the same controller. That's how you can have active states on the parent of a child page.
